STRAIGHT BASELINES: THE PHILIPPINES
On June 17, 1961 the Government of the Philippines approved Republic Act No. 3046, "An Act to Define the Baselines of the Territorial Sea of the Philippines." The preamble stated:
AN ACT TO DEFINE THE BASELINES OF THE TERRITORIAL SEA OF THE PHILIPPINES
Whereas, the Constitution of the Philippines describes the national territory as comprising all the territory ceded to the United States by the Treaty of Paris concluded between the United States and Spain on December 10, 1898, the limits of which are set forth in Article III of said treaty together with all the islands embraced in the treaty concluded at Washington, between the United States and Spain on November 7, 1900, and in the treaty concluded between the United States and Great Britain on January 2, 1930, and all the territory over which the Government of the Philippine Islands exercised jurisdiction at the time of the adoption of the Constitution.
Whereas, all the waters within the limits set forth in the above-mentioned treaties have always been regarded as part of the territory of the Philippine Islands;
Whereas, all the waters around, between and connecting the various islands of the Philippine archipelago, irrespective of their width or dimension, have always been considered as necessary appurtenances of the land territory, forming part of the island or internal waters of the Philippines;
Whereas, all waters beyond the outermost islands of the archipelago but within the limits of the boundaries set forth in the aforementioned treaties comprise the territorial sea of the Philippines;
Whereas, the baselines from which the territorial sea of the Philippines is determined consist of straight lines joining appropriate points of the outermost islands of the archipelago; and
Whereas, the said baselines should be clarified and specifically defined and described for the information of all concerned; Now, therefore,
Be it enacted by the Senate and House of Representatives of the Philippines in Congress assemblage.
Sec. 1. The baselines for the territorial sea of the Philippines are hereby defined and described specifically as follows: Sections 2 and 3 read as follows:
3
Sec. 2. All waters within the baselines provided for in Section one hereof are considered inland or internal waters of the Philippines.
Sec. 3. This Act shall take effect upon its approval.
Approved, June 17, 1961. It was later discovered that certain typographical errors existed in the discription and the Section 1 of the Act was amended to read as follows:

SEC. 2. This Act shall take effect upon its approval.
Approved.
The Act was approved on May 18, 1961 as "An Act to Define the Baselines of the Territorial Sea of the Philippines."
The United States protested the Act by Embassy Note No. 836 of May 18, 1961 declaring inter alia "...the United States Government could not regard claims based on the present legislation as binding upon it or its nationals."
The Philippines, as may be seen from the preamble, considers all waters within the baselines to be internal waters and all waters between the baselines and the so-called "Treaty Limits of the Philippines," as amended, to be territorial sea. In the southwest, the two sets of lines virtually coincide in one place while in northeast the maximum distance between the two systems of lines is approximately 285 nautical miles.
The Philippines is not a party to the Geneva Convention on the Territorial Sea.
Analysis
The Government of the Philippines has adopted the so-called "archipelago principle" in drawing a series of 80 straight baselines about the external group. [(NOTE: 64 are numbered but an additional series are suffixed with a) and b).] The length of the system is 15,139,910 meters; i.e., 15,139.910 kilometers or 8,174.8974 nautical miles. Thus the average length of a segment is 102.185 nautical miles. The longest baseline segment is 259,400 meters or 140.05 nautical miles. The segment, No. 26, connects 3 rocks awash (6º 09' 39" N; 124º 13' 02" E.) with Tongquil Island (6º 00' 15" N; 121º 52' 45" E). The line encloses the Moro Gulf. The shortest baseline, Line 63 extends 237 meters (.1279 n.m.) from Y'ami West to Y'ami Middle in the extreme north.
The baseline system, in effect, closes the important Surigao Strait Sibutu Passage, Balabac Strait and Mindoro Strait as well as the more "internal" passages through the Philippine Islands. The largest body of water enclosed is the Sulu Sea but other significant seas, the Moro, Mindanao, Sibuyan, etc., are also within the system.
The Indonesian island of Pulau Miangas, in the extreme southeast, is contained within the Philippine territorial sea and the Indonesian Straight baselines.
While the straight baseline system connects the outermost points of the islands, and by definition, follows the "general trend", the effect of the system can be best illustrated by area figures. The approximate land area of the Philippines is 115,600 square (statute) miles or 87,278 square nautical miles. The area contained within the straight baselines measures 328,345 square miles or 247,845 square nautical miles. The enclosure system therefore increases the national "territory" approximately 2.8 fold. The resulting land
10
(115,600 square miles) to water (328,345 - 115,600 = 212,745 square miles) ratio is approximately 1:1,841.
The use of the treaty limits as the territorial sea boundary would raise the total Philippine area to 702,460 sq.mi. or 530,239 sq. nautical miles increasing by more than 2.14 the "territory" within the baselines. The ratio of land and internal waters to territorial sea (374,115 sq. mi.) is 1:1,139 while the land to territorial sea ratio is 1:3,236. The ratio of land to territorial and internal waters is approximately 1:5,065.
